THOMAS J. MARCH, OF LIMERICK STATION, PENNSYLVANIA.

STOVE.

SPECIFICATION forming part of Letters Patent No. 243,075, dated June 21, 1881.

Application filed January 27, 1881.

a To all whom it may concern Be it known that I, THOMAS J. MARCH, of Limerick Station,in the county ofMontgomery and State of Pennsylvania, have invented certain new and useful Improvements in Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable'others skilled in the art to which it pertains to make and use it,

reference being bad to the accompanying drawings, which form apart of this specification.

My invention relates to an improvement in stoves.

The object is to provide an improved open Franklin reservoir-stove, constructed on scientific principles, peculiarly adapted to all heating purposes, and arranged to utilize the largest per cent. of the heat of combustion without anydisagreeable effect of the gases, smoke, and other products thereof.

With these obj ectsin view, my invention consists in certain details of construction and combinations of parts, as will hereinafter be described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in vertical section from front to rear of a stove constructed in accordance with my invention. Fig. 2 is a vertical section from side to side thereof. Fig. 3 is a view in front elevation, and Fig. 4 is a plan view of the stovebottom.

Let A represent a magazine for fuel, and by means of which a constant supply of fuel will descend into the fire-box B, over which it is situated, as fast as the fuel therein is consumed. This magazine-chamber is of oblong shape, wider at the top than at the bottom, presenting the face of its longest dimension to the front of the stove, and adapted to be removed therefrom when it is desired to change it from a coal to a wood burning stove. In the event of any gas being generated in the'magazine by reason of a partial coking of the fuel therein contained during an intensely hot fire, or being present in the magazine from other effects and causes, outlet is made therefor through apertures O, at the top of the magazine, which communicate with an inclined passage, I), located between (No model.)

located when not employed to heat apartments above, through flue 0, attached to collar D, located at the rear of the stove.

The fire-box B, located directly under the reservoir, is formed of front and rear walls, 0 and D and side walls, D D. The front wall, 0 is surmounted by fingers B which increase the capacity of the fire-box and permit free ingress of air to the fuel. I

Small perforations B in the front and rear walls of the fire-box, and shown in Figs. 1 and 30f the drawings, admit small quantities of heated air to the fire-box, which, mingling with the fuel, aids in consuming the smoke and products of combustion.

0 represents an ash hopper, by means of which the ashes as they fall from the fire-box are directed into the ash-pit D formed thereunder, and into which entrance is had by a door, A, located on the side of the stove and provided with draft-openings B, as shown.

0 represents a dust or check damper consisting of a number of perforations, D in the front wall of the ash-pit and governed by a sliding plate, a, by means of which the said perforations are wholly or partially closed and the entrance of draft from the flue A to the ash-pit is regulated.

\ B represents a plate which extends across the front of the stove and forms the outer wall of the flue A The lower edge of the said plate rests on the inner edge of the hearth 0 while the upper edge thereof rises nearly or quite to the top of the front wall, 0 of the fire-box B. As before described, this plate forms the outer wall of the flue A and hence is heated intensely hot by the draft-current passing therethrough. In order that the plate may not be injured by being thus heated, and to prevent it from being warped or becoming misshapen, it is provided with a series of horizontal ribs, b, which are made integral with or at tached to it.

One or more illuminated doors, D are mounted upon the top of the plate B and have their upper extremities engaged with the upper casing, A, depending from the cap of the edge of the door rests on ledge a formed on the inner face of plate B near its upper edge, while the upper edge of the door is provided with a shoulder, a, which engages with the outer face of the extreme lower edge of the casing A The door isremoved and replaced by a handle, a. The base of the stove is formed greater in width than the main body thereof and projects laterally outward on every side, forming the flues 13 This base portion 13 is broader in front than at other points, and forms a hearth for the stove. Midway of the length of the hearth a loose cover, a is lo cated, by means of which the hot current of air passing through the hearth, which is, in fact, a smoke-flue, may be utilized.

Two plates, 0 C located in suitable positions in the front of the bottom of the stove, operate to deflect the smoke and draft through the flues on each side of the stove, conveying it to a vertical flue, D, from which it is discharged into the chimney.

A hot-air flue, B, interposed between the rear wall of the fire-box, and the vertical flue D is adapted to supply heated air to an apartment above through collar D and pipe (7, or to the room in which the stove is situated through passage A when deflected thereunto by the damper 0 located in the collar D. The manipulation of a damper, (1, changes the path of the draft in such manner that the stove will radiate either the maximum or the minimum quantity of heat. If, for instance, the damper d is opened the draft will take the direction of the arrow to, and will heat the stove but very little, while, if the damper is closed, as seen in the drawings, the draft will take the course indicated by the arrows I), be deflected by the plates 0 G, and, passing through the flues B 13", between which the ash-pit is interposed, and from them rising through vertical flue D", be finally discharged into the chimney. A damper, c, conveniently located in front provides communication with the room wherein the stove is placed and the hot-air passage A.

- When it is desired that the air heated in the flue B shall ascend to apartments above, the damper 0, located in the collar D, is opened. When, on the contrary, it is desired to use this heat in the room in which the stove is located the damper c is closed and the damper c is opened.

It is apparent that as the front of the stove is heated it will radiate its heat out into the room while the rear portions of the stove are comparatively cold. An admirable resultis thus effected,for the heat is utilized to the best advantage, and the danger of setting fire to the wood-work adjacent to the rear of the stove is diminished. Again, the stove is of less height than most reservoir-stoves, and the operation of filling the reservoir is very easily accomplished. A stove constructed according to my invention is simple, easy of operation, and

economical in use, inasmuch as a greater per cent. of the heat of combustion is utilized than by any stove now used.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a stove, the combination, with a fire-.

box the front and rear walls whereof are provided with vertical air-passages, of finger s mounted on the front wall of the fire-box, substantially as set forth.

2. In a stove, the combination, with a firebox the front and rear walls whereof are pro vided with vertical air-passages, of fingers mounted on the front wall of the firebox, a ribbed outer casing, as described, and an interposed space between the front wall of the fire-box and said casing, forming a draft-flue, substantially as set forth.

3. In a stove, the combination, with an outer casing the lower edge of which rests upon the stove-hearth, of a series of horizontal ribs attached to or made integral with the outer face of that portion of said casing which extends across the front of the stove, substantially as set forth.

4:. I11 a stove, the combination, with an outer casing the lower edge of which rests upon the stove-hearth, of a series of horizontal ribs attached to or made integral with the outer face of said casing, and doors (one or more) adapted to be mounted on the upper edge of the casin g.

5. In a stove, the combination, with an outer casing the lower edge of which rests upon the stove-hearth, of a series of horizontalribs attached to or made integral with the outer face of the said casing, and a shoulder formed on the inner face of the upper edge thereof, and a door adapted to rest and be supported on said shoulder.

6. In a stove, the combination, with an outer casing the lower edge of which rests upon the stove-hearth, a series of horizontal ribs formed on the outer face of said casing, and a shoulder formed on the inner face of the upper edge thereof, of a door the lower edge of which is supported by the shoulder aforesaid, and a plate depending from the top of the stove and adapted to engage with the upper edge of the door.

7. In a stove, the combination, with the front walls of the fire-box and a horizontally-ribbed outer casing arranged, as described, to form an intervening flue, of a laterally-projecting hearth and two deflecting-plates located within the base-flue and arranged with their outer edges converging toward each other, substantially as set forth.

In testimony thatI claim the foregoing I have hereunto set my hand.
